GEORGE KENNY, OF NASHUA, NEW HAMPSHIRE.- Letters Patent N 0. 88,720,dotted April 6, 1869.

IMPROVEMENT IN CARRIAGE-RUSS.

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern: Be it known that I, GEORGE KENIIY, ofNashua, in

the county of Hillsborough, and State of New Hampshire, have inventedcertain Improvements in Wheel,- Hubs; and do hereby declare thefollowing to be a full, clear, andexa'ct description thereof, referencebeing had to the accompanying drawings, in which Figure 1 represents myimprovedwheel-hub in perspective Figure 2 represents a section ofwheel-hub, with spokes inserted.

The subject of my invention is an improvement on an invention for whichLetters Patent were granted me by the United States, August 18, 1868,which'embody the principles of this improvement; .but I wish to add tothe invention thus secured, by improvements, which will render itapplicable to hubs used in constructing velocipedes, and when a doubleset of spokes is required in carriage-wheels.

The invention,alreadyreferred to and patented, consists of a metallicring, provided with sockets for spokes, and screw-threads on inside,this metallic ring being screwed upon the wood part of a hub.

The nature of this invention, which forms the subject of the presentapplication, consistsv in driving a metallic ring, or flange, suppliedwith a double set of v sockets, corresponding to the mortises of the hubupon the hub, thereby enabling a builder to use a much smaller hub, and,at the same time, a much stronger and more durable one, while a doubleset of spokes may be used, thus securing a wheel, the rim of which isbraced from both sides. The advantage of this construction will be seenat once.

In the drawings- A is a metal ring, or flange, having sockets a a b 72arranged around the periphery in alternate parallel order.

, This ring is driven on to the wood part, m, of'a hub B, and for thispurpose, the bore 0 of ring A is made slightly tapering, as shown infig. 2. Driving this ring on, in paint, holds the wood perfectly tight.

The wood part of the hub is provided with mortises, which, of course,correspond with the sockets in the ring.

When the spoke's'cl d are set in a hub constructed in this manner, theybrace the wheel from both directions, as indicated in fig. 2, being asthey are set apart at the hub, but coining into a straight line, markedby the'wheel-rim. This gives a strong wheel, one that will standstraight Without dishing, and what is needed in constructing wheels forvelocipedes and carriages, but more'especially for velocipedes.

The tenons of the spokes are constructed to fit the mortiseof the woodpart of the hub, and the shoulder above the tenon; that is, the part atE is bevelled, to fit the socket in the metal.

What I claim, therefore, as my invention, and an improvement on, myLetters Patent of August 18, 1868, No. 81,175, is

The taper-bored metallic ring A, provided with'sockets a an b 1), aroundtheperiphery of the ring, in alternate parallel order, correspondingwith the mortises in the wood part of the hub, the spokes fitting intothe" sockets, and tenoned into the wood, substantially as and for thepurposes herein set forth,-

In testimony whereof, 'I have signed my name to this specification, inthe presence of two subscribing witnesses.

GEO. KENNY.
